Polypropylene/filler nanocomposites by melt compounding and in situ polymerization
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The properties of polymer nanocomposites depend greatly on the chemistry of the polymer matrices, the nature of the nanofillers, and the way in which they are prepared. Understanding the synthesis–str ...
Solution isomerization of commercial C2-symmetric metallocene catalysts
(Stellenbosch : University of Stellenbosch, 2006-03)
This study concerns the investigation of the isomerization of different metallocene catalysts in solution, and the effects thereof on the microstructure of polypropylenes prepared with these catalysts. Two C2 symmetric ...
